FLEXURAL BEHAVIOUR OF REINFORCED CONCRETE BEAMS .

The results show that fly ash aggregate concrete beams can satisfy the serviceability requirements of deflection and cracking, and that they possess adequate ductility and load factor against flexural failure. It was found that a better estimation of short term deflection can be obtained if the contribution of the concrete in tension is neglected.

Why use Fly Ash and Slag in Concrete?

Less water is needed to make the concrete workable, maximizing the strength while maintaining the workability. Although set times are prolonged with fly ash, in just 28 days, the strength of the concrete will surpass the same mix without the fly ash. Slag is similar to fly ash in that it is finer than standard Portland cement and is also
